This command will probably remove some of your previous routing setup.

After this one, there will be a short delay (depends on your bridge
configuration, but about 30 sec with defaults) when the bridge code
(STP) tries to figure out network configuration. During this period data
frames are not sent or received. If you look at kernel log ('dmesg'),
you should see the interface state changing from learning to forwarding
and after this the interfaces should be working again.

Yes, you will need to restore your correct routing setup after this. At
least setup default gateway again.
